Description

【０００１】
【発明の属する技術分野】
本発明は、浴室内の換気、または乾燥を行う浴室用換気乾燥機に関するものである。
【０００２】
【従来の技術】
近年、浴室の換気、または乾燥を行うための浴室用換気乾燥機が普及されており、浴室用換気乾燥機の施工性向上への要求が高まってきている。
【０００３】
従来、この種の浴室用換気乾燥機の一例として図１１に示すものが知られている。以下、その構成について図１１〜図１４を参照しながら説明する。
【０００４】
図１１〜図１４に示すように、浴室の壁部１０１を貫通されるように設置されるダクト１０２と、浴室の外壁に設置され、ダクト１０２に接続されるアダプター１０３を設けた換気装置取り付け板１０４と、換気送風装置１０５と、換気送風装置１０５を覆い換気装置取り付け板１０４に取り付けられる換気カバー１０７と、浴室内に設けられ、ダクト１０２に接続される温風装置取り付け板１０９と、温風装置取り付け板１０９に取り付けられ、浴室内の空気を加熱循環させる温風装置１０８とにより浴室用換気乾燥機を構成していた。
【０００５】
換気装置取り付け板１０４には、換気装置取り付け板１０４と換気カバー１０７のすきまから入った雨水がアダプター１０３に接続されたダクト１０２内へ侵入するのを防止するためにアダプター１０３と換気送風装置１０５の間に四角形状で屋外側に突出する水侵入防止壁１０６を設け、温風装置１０８と換気装置１０７を電気的に連動させるための電線１１０、および温風装置１０８の熱源に熱媒を送る温水配管１１１は、ダクト１０２内を通り、換気装置取り付け板１０４の水侵入防止壁１０６に設けられた切り欠き部１１６を通って換気カバー１０７の側部に設けられた電線・配管取り出し口１１７から屋外に取り出される。換気装置１０５には換気装置１０７内に設置される制御部品１１２を湿気から保護する制御部品ケース１１３が設けられ、換気送風装置１０５の吐出口近傍にはシャッター１１４とその軸１１５が設けられていた。
【０００６】
【発明が解決しようとする課題】
しかしながら、前記の従来の浴室用換気乾燥機の構成によれば、雨水などが、換気カバー１０７内に侵入し、水侵入防止壁１０６の天面に水が滞留したり、水侵入防止壁１０６を乗り越えて、ダクト１０２内へ水が滞留したりして、これらの滞留した水がスライム状になって異臭を放つという課題があった。
【０００７】
また、換気カバー１０７内の制御部品１１２を水の侵入から保護するために、制御部品１１２を覆う保護ケース１１３を設ける必要があった。
【０００８】
また、換気カバー１０７に設けられた電線・配管取り出し口１１７はある一定の大きさであるため、温水配管１１１または電線１１０の外径の違いやその本数によって、屋外に取り出される換気カバー１０７の電線・配管取り出し口１１７において大きな隙間ができてしまう場合があり、換気カバー１０７内に水が侵入しやすくなるという課題があった。
【０００９】
また、換気送風装置１０５を運転したとき、その吐出口近傍に設けたシャッター１１４の軸１１５に強い風が当たることによって、シャッター１１４と軸１１５の振動による騒音が発生していた。
【００１０】
本発明は、前記従来の課題を解決するもので、水が滞留することによるスライムの発生を防止した浴室用換気乾燥機を提供することを目的とする。
【００１１】
また、水の侵入を防止するために制御部品を保護する保護ケースを設ける必要のない浴室用換気乾燥機を提供することを目的とする。
【００１２】
また、換気カバー内の水の侵入を防止し、配管または電線の引き回しまたは取り出しを容易にした浴室用換気乾燥機を提供することを目的とする。

【００３２】
以下、本発明の実施の形態について図１〜図１０を参照しながら説明する。
【００３３】
（実施の形態１）
図１〜図８に示すように、本発明の浴室用換気乾燥機は、浴室の壁を貫通するダクト１と、ダクト１に接続されるアダプター２を設け、横幅２０５ｍｍ以下、高さ１５５ｍｍ以下の角穴を覆い隠すことができ、浴室の壁に設置される空調装置取り付け板３と、空調装置取り付け板３に設置され、浴室内の空気を循環、加熱循環、または除湿循環する空調装置４と、ダクト１に接続されるアダプター５を設け、横幅２０５ｍｍ以下、高さ１５５ｍｍ以下の角穴を覆い隠すことができ、外壁に設置される換気装置取り付け板６と、換気装置取り付け板６と一体となって屋外に設けられ、浴室内の空気を換気するための換気装置１３とから構成される。換気装置１３は、換気ファン７を駆動する換気ファン駆動用モータ８および内部に換気ファン７を収納した換気ケーシング１０と、これらの間に介在して支持固定するための換気ファン駆動用モータ固定板９とから形成される換気送風装置１１と、換気送風装置１１を覆い換気装置取り付け板６に取り付けられる換気カバー１２とから構成される。
【００３４】
換気装置取り付け板６にはほぼ中央に穴が開いており、アダプター５はこの穴を中心に設けられ、アダプター５と換気送風装置１１の間には、水侵入防止壁１４が設けられている。水侵入防止壁１４は、内側壁と外側壁を有する二重の壁構造であり、換気装置１３を施工するときに水侵入防止壁１４に換気送風装置１１を合致させた場合には、外側壁は換気ケーシング１０の吸込み口側の端面の外形よりも小さく、かつその外形に略一致するように形成され、内側壁は、換気ケーシング１０の吸込み口よりも大きく、かつ吸込み口に略一致するような形状で形成されている。水侵入防止壁１４は、外側壁の上部側の外周面が、中央より両側が下がって形成され、または中央から両側にかけて下り勾配に形成されている。また、水侵入防止壁１４の形状は略円形状で形成されていてもよい。水侵入防止壁１４には、電線１５、または空調装置４の熱源に熱媒を使用する場合の温水配管２４を通すための切り欠き部１６、１７、１８が数カ所設けられ、切り欠き部１６、１７、１８には水侵入防止壁１４の高さ、奥行き、幅に略等しい寸法のシール材１９が貼られている。換気ファン駆動用モータ固定板９の外周縁は、換気カバー１２を換気装置取り付け板６に取り付けたときに換気カバー１２に密着または、密着に近い状態になるような形状で形成されており、換気カバー１２と換気ファン駆動用モータ固定板９で囲まれた密閉された、または密閉に近い空間内に制御部品２０は配置されることになる。
【００３５】
換気ケーシング１０には、その通風路内にシャッター２１が配置され、シャッター２１の軸２２から、換気ファン７の外周へ引いた接線上に何らかの障害物が存在するように軸２２を設け、または、換気ケーシング１０の通風路内であって、舌部２３の一部に窪みを作り、その位置に軸２２を設ける。
【００３６】
浴室内に設置された空調装置４に接続される電線１５や温水配管２４は、アダプター２を通ってダクト１内に入り、ダクト１内を通ってアダプター５に入り、シール材１９と換気ケーシング１０の吸込み口側の端面との間に押し挟まれた状態で、換気装置取り付け板６の切り欠き部１６、１７、１８のいずれかを通って換気カバー１２に設けられた電線・配管取り出し部２５から屋外へ取り出される。
【００３７】
上記構成において、屋外に設けられる換気装置１３に雨水が降り注ぐと、換気カバー１２と換気装置取り付け板６との間から雨水が浸入して、換気カバー１２の内側に侵入することとなるが、水侵入防止壁１４シール材１９によって雨水がダクト１内にまで侵入することが防止され、また、水侵入防止壁１４の外側壁の上部側の外周面に落ちた雨水は、その中央より両側が下がって形成されているため、両側へ流れ落ち、換気カバー１２の下部に設けられた開孔（図示せず）から屋外へと排出されることとなる。
【００３８】
また、換気カバー１２と換気ファン駆動用モータ固定板９で防水または防滴空間を作ることができるので、雨水の制御部品２０への付着が防止できることとなる。
【００３９】
また、換気ケーシング１０内の通風路内の窪みにシャッター２１の軸２２を設けたので、シャッター２１と軸２２の振動による騒音をおさえることができる。
【００４０】
このように本発明の実施の形態１の浴室用換気乾燥機によれば、水侵入防止壁１４に換気送風装置１１を合わせた場合に、その外側壁は換気ケーシング１０の吸込み口側の端面の外形よりも小さく、かつその外形に略一致するように形成され、内側壁は、換気ケーシング１０の吸込み口よりも大きく、かつ吸込み口に略一致するような形状で形成されているので、水侵入防止壁１４の外側壁と内側壁の距離を最大限に取ることになり、換気装置取り付け板６と換気カバー１２のすきまから換気装置１３内に雨水が侵入した場合、その雨水がダクト１に侵入するまでの沿面距離を最長にすることができ、ダクト１への雨水の侵入を困難にすることができる。
【００４１】
また、水侵入防止壁１４の上部側の外周面が、中央より両側が下がって形成され、または中央から両側にかけて下り勾配に形成されていることにより、換気カバー１２内に侵入した雨水が水侵入防止壁１４の上部側の外周面を両側へ流れて行くので、水侵入防止壁１４の上部側の外周面に雨水が滞留することがなくなり、水侵入防止壁１４と換気ケーシング１０の当接部分のすきまからダクト１への流れ込みをなくしたり、滞留した雨水がスライムに変化して異臭を放つことを防止することができる。
【００４２】
また、換気ファン駆動用モータ固定板９の外周縁を、換気カバー１２を換気装置取り付け板６に取り付けたときに換気カバー１２に密着、または密着に近い状態になるような形状で形成することにより、換気カバー１２と換気ファン駆動用モータ固定板９で囲まれた密閉、または密閉に近い空間を形成することができ、その空間内に制御部品２０を配置することで制御部品２０の防水または防滴となり、別途制御部品２０のための保護カバーなどの防水用の部品を不必要とすることができる。
【００４３】
また、浴室の壁に外周が横幅２０５ｍｍ以下、高さ１５５ｍｍ以下の既存の角穴または、直径が１５５ｍｍ以下の既存の丸穴を覆い隠す空調装置取り付け板３に設けられたアダプター２と、前記角穴または、丸穴を覆い隠す換気装置取り付け板６に設けられたアダプター５でダクト１をはさみこむことにより、ダクト１を宙空に浮かせた状態で設置することができるので、前記角穴または丸穴が既存している場合でも、その穴を塞がずに、そのまま施工ができる。
【００４４】
また、換気ケーシング１０の通風路内に設けられるシャッター２１の軸２２を、換気ファン７の外周へ引いた接線上に何らかの障害物が存在するように設けることにより、軸２２に換気の風が直接当たらなくなり、シャッター２１と軸２２の振動を減少することができ、振動が減少することでシャッター２１と軸２２の干渉による騒音を低減することができる。
【００４５】
また、換気ケーシング１０の通風路内であって、舌部２３の一部に窪みを設け、その位置に軸２２を設けることにより、軸２２に換気の風が直接当たらなくなり、シャッター２１と軸２２の振動を減少することができ、振動が減少することでシャッター２１と軸２２の干渉による騒音を低減することができる。
【００４６】
（実施の形態２）
図９および図１０に示すように、実施の形態１の図１における電線・配管取り出し部２５を、半径約４．５ｍｍの半円状の電線取り出し部２６をその内部に設けた少なくとも２つの取り出し口を有する配管取り出し部２７により形成する。配管取り出し部２７は換気カバー１２Ａの側面の複数箇所に設ける。
【００４７】
水侵入防止壁２８は、前後方向の壁高さが１７．５ｍｍ以上３０ｍｍ以下に形成され、周方向の幅が約４８ｍｍ以上７０ｍｍ以下の切り欠き部２９、３０、３１を複数箇所形成する。
【００４８】
なお、配管取り出し部２７および電線取り出し部２６は、換気カバー１２Ａの側面に薄肉部１２ａを有する半抜き状に形成され、必要に応じて配線、配管等を通すためにカッターなどで開口されるものであり、電線等の施工前は閉じられているものである。
【００４９】
上記構成において、電線取り出し部２６を少なくとも２つの配管取り出し部２７に設けることにより、換気カバー１２Ａから電線１５と配管３２を異なる方向に取り出すことができる。また、水侵入防止壁２８の壁高さを１７．５ｍｍ以上３０ｍｍ以下、切り欠き部２９、３０、３１の幅を４８ｍｍ以上７０ｍｍ以下にすることにより、細い電線だけでなく太い断熱材を持つ冷媒配管も引き出すことができる。
【００５０】
このように本発明の実施の形態２によれば、半径４．５ｍｍの半円状の電線取り出し部２６を内部に含んだ配管取り出し部２７を換気カバー１２Ａの側面に設けたことにより、電線配線のみ取り出す場合は、電線取り出し部２６を打ち抜いて使用し、温水等の配管を取り出す必要のある場合は、電線取り出し部２６の外側の配管取り出し部２７を打ち抜いて使用することができ、どちらの場合にも対応可能な換気カバー１２Ａを提供できることとなる。
【００５１】
また、電線取り出し部２６を設けた配管取り出し部２７を換気カバー１２Ａの側面に複数箇所設けることにより、電線１５と配管３２を異なる方向に引き出すことが可能となり、配管３２を接続する位置と電線１５を接続する位置が換気装置１３に対して別方向であっても無理な引き回しをしなくても引き回すことができる。
【００５２】
また、水侵入防止壁２８の壁高さを１７．５ｍｍ以上３０ｍｍ以下、切り欠き部２９、３０、３１の幅を４８ｍｍ以上７０ｍｍ以下にすることにより、太い断熱材を持つ冷媒配管も引き出すことが可能となり、電気式の空調装置だけでなく、冷媒を熱源として使用した空調装置も、換気装置１３と組合せて使用することができる。
【００５３】
